BARREL-TAP.

SPECIFICATION forming m of Letters Batent No. 629,152, dated uly 18,1899." Application at November 12, 1393. sums... 696,219. (No model.)

This invention relatesto improvements in combining barrel taps and fillers,hav ing more particular reference to those used for ale and lager-beer kegs or other liquid-receptacles where a gaseous pressure of any kind is desired, such as water or steam.

My object is to improve their detail construction and general utility; and to that end my invention consists in the several new and novel features of construction and oper-- ation hereinafter described and which are specifically set forth in the claim hereunto an nexedl It is constructed as follows, reference being had to the accompanying drawings, in which Figure 1 is a section of a fillerand interior View of a modified form of the tap, the key being slightly raised from its bearings. Fig. 2 is a cross-section of'the filler, tap, and key, showing a removable tube. Fig. 3 is a cross section on line a: to, Fig. 2. Fig. 4 is a top plan view of the filler and tap complete, the key being removed. Fig. 5 is a view of the filler complete detached.

A represents the screw-threaded bushing, which is inserted into the keg or barrel and in which is placed a cone-shaped shell a, which is secured to the bushing by meansof the screw B. In the side of the upper portion of the shell is formed the circular recess 0, in

which the lugs F, formed upon the inner side of the bushing, catch for the purpose of holding the conical shell in position and allowing it to be partially rotated before it can be removed. Insideof this conical shell a. is placed the conical plug (1, which has its lower end made screw-threaded and to project below the lower end of the shell a, so as to receive the nut G, by which it is held loosely in position. This plug has a turning movement inside of the shell, and through one side of the plug and the shell are made vertical openings 1' 1". When the plug is turned so that its opening r corresponds with the one 1' in the shell, the pipe Z can be passed through the tapdcwn into the barrel or keg for the purpose of drawing off the liquid contained 35 therein. Inorder to limit the rotation of the plug 01, a horizontal groove side, and inthis groove catches the lugs or stops formed upon the inner side of the top of the shell. The key consists of a lever provided with a handle Z, and which key is provided with suitable projections, which fit in corresponding recesses in the top of the plug, so that when a turning movement is imparted to the key through its handle the plug will be turned so as to bring its openin 1" in or out of line with the corresponding opening 0 in the shell. As seen in Fig. 1, when'the plug is turned so that the openings are out of alinement with each otherthe opening 0' in the shell is effectively closed. This tap is provided with the air-vent min the usual manner.

It will be observed that in'view of the fact that the plug (1' fits tightly within the shell a the valve is always snug upon its seat and that it is impossible for any foreign substance to remain thereinto obstruct the passage, for when the plug is rotated it will immediately cut the substance and clear itself. Before the key is inserted into the bushing the valves are closed and the key can only be inserted into the bushing when the valve is closed, and the valve can onlybe opened when the key and its connecting-tube are in the bushing, so that it will be impossible for an absent-minded'person to remove the key without closing the valve.

Having described my invention, what I claim, and desire to secure by Letters Patent,

' In a barrel-tap, the cone provided with grooves around its upper edge to engage with the lugs upon the plug, and having an opening to one sideof its center for the insertion and removal of the drawing-tube, combined with the plug also provided with'an opening to one side of its center, and through which the tube is passed when the plug andcone 'are moved into alinement; a suitable recessin the top of the plug, a key which is applied to the plug for'the purpose of turning it, and an air-vent, substantially as shown.

In witness whereof I have hereunto set my hand this 3d day of November, 1898.
